摘要
阐述了简易控制的体制,分别建立了采用脉冲或舵机实施控制的弹道模型,对2种执行机构的修正力特性进行了分析,研究了2种执行机构的控制策略.针对某型迫弹无控飞行时的试验中间概率误差约为1%,利用蒙特卡洛打靶法,在相同的计算条件下,若末段采用脉冲控制,仿真计算得到其圆概率误差小于等于4 m;若末段采用舵机控制,其圆概率误差小于等于2.5 m.结果表明,利用脉冲或舵机在迫弹的末段实施简易控制,能够大大改善其密集度,且两者的控制原理、控制过程等各有特点,对今后的工程化应用有一定的参考意义.
The system of simple control was explained. The ballistic models using impulse or rudder for control were established. The characteristics of correctional force and the control strategy of two kinds of executive equips were analyzed. Aiming to some projectiles of trench mortar, the probability error of the experiment without controlling flight is about 1%. Monte Carlo target practice was used in the same calculating condition. The calculating circle probability error is not more than 4 m under the condition of unpulse control, and is not more than 2.5 m under the condition of the rudder control. The results show that the im- pulse or rudder is feasible to implement simple control. The dispersion of projectiles of trench mortar can be greatly improved. The control principle and control process of two kinds of executive equips have their respective characteristics. The results are useful in the engineering design of projectiles of trench mortar in the future.
